From the ex-files

It is known that Preity Zinta and Kareena Kapoor have cameos in Raj and Krishna DK's next, Happy Ending, which features Saif Ali Khan in the lead. Mirror has now learnt that the two actresses will play former lovers of Saif's character in the film.

Revealed a source close to the production, "The director duo were looking for actresses whose romantic camaraderie with Saif has clicked in the past. It was Saif who suggested Preity's name who has successfully paired with him twice in the past (Kal Ho Na Ho and Salaam Namaste)."

The source adds that Saif personally called up Preity and asked her if she'd be interested in playing his ex-girlfriend. She laughed and agreed. "Her character is the anchor in Saif's life. He plays a successful author struggling with a writer's block," says the source.

On the other hand Kareena, who also has a cameo, will play a dramatically different character. "She is more of an obsessive lover and her part is much smaller than Preity's," adds the source.

When contacted, Krishna DK said: "Yes, Saif called Preity and it was sweet of her to agree. Bebo's inclusion was more of a spontaneous decision as she was with Saif in Los Angeles where we were shooting."
